,CANADA, A CORPORATION OF CANADA 'EYEron ANCHOR nons, EYE BoL'rs, ANDTHE LIKE Application filed May 25,1931, Serial No. 539,991, and inCanada June 17, 1990.

Ourinvention relatesto improvements in eyes for anchor rods,'eye boltsand the like, and is particularly constructed for the recep- I tion ofguy wires. I 6 The object of our invention is to construct an eyeincorporating a rotatable member which will rotate as the guy wire isdrawn therearound in being tightened up, and a'furtherfobject of ourinvention is to provide \0 means for locking the rotatable memberagainst rotation when the guy wire istightened and secured so that anypossible slippage of the guy Wire after it is tightened has to overcomefriction between the locked rowire loop extending therearound. @Anotherand particular object of our invention is to furnish a clamping boltupon which the rotatable member is freely mounted and which whentightened up clamps the rotatable member against one leg of the bifidportion of the eye inwhich it is mounted to lock such rotatable memberagainst rotation. 7 Our invention consists of an eye of the characterdescribed, constructed and arranged all as hereinafter more particularlydescribed and illustrated in the accompanying drawings in which Fig. 1is a front elevational view of the 0 upper portion of an anchor rodshowing our eye formed upon the end thereof, and the guy wire loopextending therethrough.

Fig. 2 is a side elevational view of the construction shown in Fig. 1,a'portion of the guy-wire loop only being -shown.

Fig. 3 is a perspective view. of a fragmentary portion of the leg ofthe'bifid portion of our eye against which the rotatable memher isclamped.

Fig.4 is a similar view to Fig. 3, showing aifragmentary portionof theother leg of the bifid portion. I 4

, Fig. 5 is a perspective view of the bolt upon which the rotatablemember is mounted, and

Fig. 6 is a perspective view of the rotatable member or spool.

Like characters of reference indicate correspondingparts in thedifferent views in the drawings.

Our eye which is formed upon the end of an anchor rod or eye bolt 1consists of a bifid portion formed upon the end of the rod, eitherintegrally as shown, or as a separate member connected thereto in anysuitable manner, and 2 is a spool rotatably mounted between the legs 3and 4 of the bifid portion in the vicinity of their outer ends. Thespool 2 is formed with a guy Wire receiving groove 5 around which theguy wire 6 extends, the groove being substantially semi-circular, and

of slightly larger diameter than the diameter of the guy wire which itis adapted to receive, it being understood that the guy wire is made upof a plurality of strands as shown in the drawings.

The spool 2 is formed with a central orifice 7 and freely mounted upon abolt 8 extending across the bifid portion through orifices 9 and 10 inthe legs 3 and 4 respectively. The bolt 8 is formed with a shoulder 11of greater length than the diameter of the bolt and formed between theinner end of the bolt and its head 12. The shoulder has round ends andis contained within the orifice 9 in the leg 3, such orifice being ofthe same shape as the shoulder so that the bolt is held againstrotation.

Upon reference to Fig. 2 it will be seen that the spool 2 is of lesswidth than the distance between the legs 3 and 4 between which it ispositioned, and also the shoulder 11 is of a greater thickness than thethickness of the leg 3, so that it projects inwardly beyond the innerface of such leg to bear against the adjacent'side of the spool when thenut 13.is

' wire and the spool, as is the case in all other the spool are drawninto contact with the serside of the spool to press the other side ofthe spool against the serrated face 15. In this way the spool is freeupon the bolt 8 and will rotate as the guy wire is tightened up.

The guy wire is drawn taut by exerting a pull uponits free'end whichhas'been passed around the spool and as such spool is free to rotatethere is no frictional drag between the types of eye constructionwherein the wire receiving face is permanently stationary. 7 When theguy wire'is drawn to the requlred V tautness, the vend of the wire issecured to the main portion by any suitable clamp 16 and the nuns uponthe bolt "8 tightened up so :that .the shoulder :ll'upon thebolt 8engages the side of the spool and draws such the inside and outsidestrands, as is Very often the case in drawing a stranded wire around acircular rigid face.

By permitting the spool to rotate whenthe guy wire is being tightenedupthe galvanizing or other protective coating upon the spool will notbescraped Off as the wire will not drag along the face of thespoolduring the tightening operation.

If it is desired to-reset or retighten the wire at anytime it isonlynecessary to loosen the clamp 16 and then to slacken the nut 13 andknock the bolt slightly in the direction of the leg 3, so that the boltshoulder 11 does not retain the spool in close contact with the serratedface 15.

In cases where it is desirable to have two or more guy wires extendingfrom one eye the bifid portion is or formed of a greater width, so thatthe legs 3vand 4 permit the free insertion of the desired'number ofspools therebetween, a longer bolt 8 of course being furnished. When thenut.13 on the bolt 8 'is=tig'htened up the sh'oulderll bears against theoutside face of the adjacent spool, drawing the abutting serrated spoolfaces torated face 15 of such leg so that the whole assembly is lockedagainst rotation.

From the foregoing description it will be seen that we have devised aneye for anchor rods, eye bolts and the like in which there is nodistortion of the spool supporting bifid portion when the spool isclamped thereto, so that the spool may be at any time released to freelyrotate, and although we have shown and described a particular embodimentof our invention wherein we have shown a particular construction forrotatably mounting our eye and also for securing such eye againstundesired rotation, it islto-ibe understood? that we can makesuchchangesand alterations as we may from time to time deem necessary withoutdeparting from the spirit of our invention as set forth in the appendedclaims.

What we claim as our invention. is
